Planning electrical systems to be future-proof

What exactly is all connected there?

What do you mean here? How my network infrastructure looks?

On the ground floor, I have two double sockets in the living room at the possible TV spots. Additionally, an access point on the ceiling, a connection for the Doorbird indoor station in the hallway, and an access point on the exterior wall for the Doorbird outdoor station.

On the upper floor, there is a double socket in each of three rooms, plus an access point on the ceiling and a single socket in the hallway.

On the ground floor, in a larger room, again two double sockets, in a small room one double socket, an access point on the ceiling, and a single socket in the hallway.

Everything comes together in the basement. In the network cabinet, I also have a NAS, the Fritzbox, and an I/O controller for the Doorbird station.

In hindsight, I would plan a few small things differently. For example, nowadays practically all devices are equipped with Wi-Fi, and if you ensure very good Wi-Fi coverage, in my opinion, you don’t need double sockets—single sockets as a backup will suffice. At most, only where you are sure a PC/printer or the TV equipment will be placed. But even there, it’s already optional. Rather, one single socket in different spots in the room if you don’t yet know, for example, where desks might be placed.

One access point per floor is also almost overkill, especially if some floors (like our attic) are rarely used for work. At least, I have since figured out how to script-control to really switch off the Unifi access points via PoE shutdown. If necessary, you could initially just close the ceiling at that spot with a blank cover.

The Doorbird is another chapter. Overall, I am only moderately satisfied with it. Also, I think I wouldn’t have needed the I/O controller, as this task apparently could have been handled by the indoor station.

But these are essentially minor details. I enjoy the great infrastructure every day, which offers me so much flexibility. And because you cannot foresee everything in planning, I would always prefer to plan somewhat generously rather than too sparingly.

One access point per floor is also almost overkill, especially when some floors (like our attic) are rarely used for work.

I had the opposite experience. I would have liked to install 2 APs diagonally on the upper floor instead of 1 centrally. With the wall heating, I block a lot. Although I might still gain some range if I disable the 5 GHz requirement for the high-performance devices, which I think was enabled by default on Ubiquity.

One access point per floor is almost overkill,

I cannot agree with that statement in 2021. I see it more as a minimum - if you want Wi-Fi at all. It does not have to be the ceiling-mounted access point, but with the strong trend toward higher frequencies due to higher speeds, you won't achieve much with just one access point for more than one floor, and the size and layout (and construction!) of the floor also matter.

I cannot let that stand for 2021. I see it rather as a minimum - if you want WLAN at all.

Clear agreement. Better more cells than higher signal strength. When transmitters and receivers work at the limit of muscle inflammation, signal deformations are amplified and the proportion of bit losses increases, requiring repeated transmission for correction, which mainly disrupts plesiochronous applications. The working atmosphere in the entire cacophony orchestra of the WLAN opera house becomes tense when unsatisfactory coverage must be "overpowered." Of all components in a typical single-family house, the reinforced concrete ceilings are the nastiest signal barriers. Therefore, I consider the design concept of viewing at least each floor level as an independent segment of demand extremely sensible. Network segments across multiple "fire sections" are, in my opinion, fundamentally attempts to save that backfire.

Full agreement, although one should consider that increasing the transmit power at the access point is usually still relatively easy (although rarely legal), but this does not help for the return channel. So you would have to amplify the antennas, which may be no less illegal, but is usually significantly more complex. Last but not least: unnecessary many retransmits cost airtime, which is not available to others using this channel, thus negatively affecting all connected devices. We have one access point per floor, except for the ground floor with two APs. This works "just about," of course more comfortably in 2.4 GHz than in 5 GHz.

We are currently also working on our electrical and network planning. Apart from self-research here and on the internet, I have little knowledge of the subject. I have followed the rule of thumb: one network outlet in the bedrooms and workrooms, as well as two by the TV in the living room. Additionally, I planned a network connection centrally in the hallway on the upper floor/bedrooms for an access point. On the ground floor, I planned two of these: one in the living area of the open plan room near the main terrace and one in the utility room right next to the north terrace.

Basically, we are not heavy users. Although my wife works from home and I work part-time in the office, we do not send/receive large amounts of data except for video conferences and streaming, for which I have intended the network connections in the work and bedrooms. The truth is, though, that we will have to decide: computer or printer connected via LAN, because so far only one network connection each is planned.

Presumably, the Fritzbox will still be housed in the technical room, right? At least, that’s what I read here. This room is directly in the basement next to my office. Would that be sufficient for Wi-Fi reception in the basement (otherwise there is only a storage room and the garage there) or would you still install an access point in the office? What do you think of my rule of thumb? I would be very happy if you could take a look at our floor plan and give me feedback.

The floor plan is in the thread "Erste Grundrissplanung auf Karopapier Hang Keller 2 Vollgeschosse" on page 10 in post #59.

Thank you in advance. :)
